Why does my furnace igniter keep burning out?

Why does my hot surface ignitor keep breaking?

High Voltage

An 80-volt HSI should have about 80 volts applied to it. Applying 120 volts to that HSI will cause it break, and sometimes almost immediately. Having too low of voltage may not let the igniter burn hot enough. Once, in my early service years, I replaced a 240 ignitor for a package unit with a 120 ignitor.

How much does it cost to change a furnace ignitor?

Ignitor. Your furnace’s ignitor plays a critical part in the start-up process. As its name suggests, it ignites the gas your furnace turns to heat. The average cost to repair or replace an ignitor is $150–$300.

How do you fix a furnace that clicks?

Loud clicking sounds can be heard when inducer blowers and fan shafts are clogged by buildup or when bearings are worn out. Bearings on the main blower motor might click as the furnace runs because the shaft is rusted or dirty. Cleaning and lubricating the fan shaft will help fix the problem and prevent premature wear.

Why does pilot not stay lit?

The Buildup of Dirt or Debris Around The Pilot Light – Over the years it’s easy for dust, debris, and dirt to build up on the inside of the intake valve where the pilot light resides. This makes it difficult for the flame to breath and as a result causes the pilot light to go out suddenly.
